The eight planets in our solar system each occupy their own orbits around the Sun. They orbit the star in ellipses, which means their distance to the sun varies depending on where they are in their orbits. When they get closest to the Sun, it's called perihelion, and when it's farthest away, it's called aphelion.

So to talk about how far the planets are from the is a difficult question, not only because their distances constantly change, but also because the spans are so immense—making it hard for a human to grasp. For this reason, astronomers often use a term called , representing the from the Earth to the Sun.

The table below (first created by Universe Today founder Fraser Cain in 2008) shows all the planets and their distance to the Sun, as well as how close these get to Earth.
